"You know the drill by now: another week, another -rc," began Linux creator, Linus Torvalds, announcing the 2.6.26-rc4 kernel. "There's a lot of small stuff in here", he continued, "most people won't even notice. The most noticeable thing is for all you 32-bit x86 people who use PAE (enabled by the HIGHMEM64G config option) due to having too much memory in your machine - mprotect() was broken due to some of the PAT fix/cleanup patches, causing the NX bit to be not set correctly." Linus described the fixed bug:
"If you had PAE enabled _and_ a recent enough CPU to have NX, but not recent enough to be 64-bit (or you were just perverse and wanted to run a 32-bit kernel despite having a chip that could do 64-bit and enough memory that you _really_ should have used a 64-bit kernel), you'd get various random program failures with SIGSEGV. It ranged from X not starting up to apparently OpenOffice not working if it did."
He went on to note, "most of the changes, as usual, are in drivers, at 60%, with some DRI changes leading the way (fixing a number of other regressions, mainly by reverting the under-cooked vblank update). Network, MMC, USB, watchdog and IDE drivers also got updates. We had CIFS and NFS updates, and some arch updates as usual." Linus concluded, "nothing really hugely exciting, I think we're doing pretty ok in the release cycle, and I'm getting the feeling that things are calming down."
